I think you have to split *B and DL here. DL is a fetish, and until diapers themselves existed it isn't possible for a fetish about them to have existed. *B however, I wouldn't be surprised if it has been around as long as society has. I have put over 1000 years because I think that the *B side of this has almost certainly been around this long. DL not nearly as long - it requires the existence of diapers themselves. Even now you can get people who are *B for whom different aspects of being infantile are more important than the diapers - people could easily have felt part of them was, or want to be, infantile without the existance of diapers. The idea of being an infant again simply needs a concept of what it is to be an infant.

EDIT: Tommy - porn - invented in the past 100 years? I doubt this greatly. I expect porn has existed in one way or another since we have been able to communicate other than through speech, and I would be surprised if before then we hadn't had erotic tales told by word of mouth. To be honest, I honestly thought they had found porn dating back to the ancient Romans, and even if they haven't I would be amazed if it hadn't existed.

SECOND EDIT: I didn't vote forever (as long as diapers have existed) because from what we know diapers haven't been around that long. Also, while I imagine fetishes etc. developed early in human society, I doubt they have existed for as long as there have been humans. I think it is a product of human society - but one that would have taken a short while to form. I imagine they reach back deep into human history, but would equally imagine it is a product of human society, not being human itself.

Reason: I wanted to add to my thoughts, that simple!

Mistaking inches for cm...like NASA did, which causes some rocket to explode?!

Either way, I'm pretty sure the desire to act younger than your actual age has been around for a long time. Just look at other animals and you'll see they do the same thing at times, so it's not really unnatural either.
